This series adds self tests to test the registers, the
msix interrupts, the tlv, and the firmware mailbox.

This series assumes that the
[PATCH net-next 0/2] Add debugfs hooks [1]
is present.

When the self tests are run the with ethtool -t:

        ethtool -t eth0
        The test result is PASS
        The test extra info:
        Register test (offline)  0
        MSI-X Interrupt test (offline)   0
        FW mailbox test (on/offline)     0
